液压马达属于能量转换装置,是能够产生连续旋转运动的执行元件。液压马达能把输送来的油液的压力能转换为机械能,其输入量是油液的压力和流量,输出量是转矩和转速(角速度)。液压马达按其结构可以分为齿轮式、叶片式及柱塞式等若干种。
Hydraulic motors are energy conversion devices that are capable of generating continuous rotary motion. The hydraulic motor converts the pressure of the delivered fluid into mechanical energy. The input is the pressure and flow of the fluid, and the output is torque and speed (angular velocity). Hydraulic motor according to its structure can be divided into gear, vane and plunger and so on several kinds.
